To all whom it may concern: alarm box.

The revolvingarma` fire. ture H is journaled in end pieces which con- My inventionconsists in a magneto-electric nect the pole-pieces F and is of theordinary 25 machine 0r generator of the usual type, apivconstruction.Upon the inner end of the oted spring-actuated yoke provided withinshaft of this armature are secured both the ternal shoulders uponopposite sides and pinion I and lug J, which revolves with the whichregulate the turning of the armature, armature and which operates iuconnection and a connecting-link extending upwardly with the pivotedyoke K for the purpose of 3o from the yoke and having its upper endpivmanipulating the armature.

These shoulders L are sooperating the said toothed wheel and which arranged that when the yokeis depressed the mechanism is set in motion either by a key or outer endof the lug J slips off from the shoulany other releasing mechanism thatmay be der behind which it was catching and after preferred. beingcarried around half a circle by the arma- 4o It still further consistsin a magneto-electure the end of the lug catches against the tricmachine or generator, a spring-actuated other shoulderL, and thusprevents the armapivoted yoke for manipulating the same, and ture fromrevolving` further until the yoke a connecting-link which extendsupwardly is again manipulated. When the yoke is defrom the yoke,combined with a lever, to pressed, the lug is released from the lower 45which the upper end of the link is pivoted, shoulder and catches on theupper one. Then and a spring-actuated wheel having projecwhen the yokerises the lug is released from tions upon its periphery, the lever andthe the upper shoulder and again catches on the yoke being operated bythe same spring, as lower one. This armature is caused to rewill be morefully described hereinafter. volve by means of the large wheel N, which10o 5o In the accompanying drawings, Figurelis is secured to thespringdrum O, provided a side elevation of a mechanism for a lirewithteeth upon its outer periphery, and

which drum each time the yoke is" manipulated causes the armature tomake half a revolution. By manipulating the yoke either through the keyM or in any other way the armature may be made to revolve so as to giveany number of electrical impulses, so as to transmit the number of thebox.

Upon the shaft P of the drum O, outside of the drum, is secured aratchet Q, with which the pawl R engages for the purpose of preventingthe spring from unwinding and with which ratchet also engages a secondspringactuated pawl S upon the lower end of the winding-lever T, andwhich lever is pivoted at its lower end upon the shaft P. After thislever T has been used in the usual manner to wind the spring in the drumO theleverT is turned up into the position shown in Fig. 2 and held outof the way by means of the catch U, lwhich engages with a pin on theside of the lever, as shown.

Pivoted to the outer upper corner of the yoke K is a rigidconnecting-link V, which is pivoted at its upper end to the lever W,pivoted at its outer end to 011e of the upper corners of the frame B,and which lever has a V-shaped projection X upon its inner end to engagewith the wheel Y, provided with projections upon its periphery toindicate the number of the box. Secured to the base at any suitablepoint is a spring` Z, which bears upon the outer lower corner of theyoke K, and thus causes the yoke to be forced upward, and the lever Whas its projection X forced upwardly against the wheel Y through therigid connecting-link V, which connects the yoke and theinnerend of thelever. Thus by a single spring I make the yoke and the lever W automaticin their action, and when the lever W is manipulated by the wheel Y theyoke K is operated at the same time, so as to allow the armature to makehalf-revolutions, and thus send impulses to headquarters, so as to givethe number of the box being operated. The wheel Y is provided withprojections upon its periphery, as shown, and which projections arearranged according` to the number of the box, and these projectionspassing over the projection X upon the'end of the lever W operate theyoke K and allow the armature to revolve. This wheel Y is operated by aspring A', having one end secured to the shaft C', upon which the wheelY is placed, and to the opposite end of the shaft from the wheel isconnected a train of gears B', which forms a step-by-step escapement forcontrolling' the speed at which the Wheel Y shall revolve in sending inthe number of the box when an alarm is given.

Extending across the top of the frame B is the endwise-moving slide D',which has the spring E'connected to one end, so as to cause the slide tomove outwardly whenever it is left free to move by the endwise movementof the slide F', which is manipulated by a key G', and which key causesthe slide F' to move sufiiciently far endwise that its end H',

which catches over the end of the slide D', is withdrawn, as shown inFigs. l and 2, to allow the slide D' to be forced outwardly the fulllength of its movement by the spring E'. Secured to this slide D' andprojecting up wardly is the post l', which moves with the slide, andfrom the top of which post projects the horizontal arm or catch J',which catches under the end of the vibrating arm K' of the escapement.As long as the slide F' is forced backwardly, as shown in Fig. l, thispost l' and its arm J' are moved backward sufliciently far to preventthe vibrator K' from engaging therewith, and hence the spring A' willcause the wheel Y to make a full revolution and thus send the number ofthe box to headquarters the number of times the group of projectionsupon its surface are repeated. As here shown, there are five sets ofthese projections, and the number of the box is transmitted iive timesto headquarters. After the wheel has revolved its full distance theprojecting` pin L' comes in contact with the stationary stop M',projecting upwardly 'from the top of the frame B. Each time the box isoperated the chief or some one in charge must open the box and throughthe thumb-wheel N', secured to the wheel Y, turn the wheel entirelyaround, ready to be operated again.

This invention difl'ers from the devices now in use only in having thewheel Y under the tension of the spring A', so that each time the box isoperated the wheel revolves once, and the spring must then be wound upagain before the wheel can be made to make another revolution.

As shown, the key G' has its operating part which engages with the slideF' bent so that after the slide F' has been forced backward into theposition shown in Fig. l the key cannot be released until the chief orone who has the box in charge comes and opens the door, when the key iswithdrawn on the opening of the door. Connected to thisslide F' is aspring O', (shown in Fig. 2,) which when the end of the slide D' isforced backward by the chief causes the slide F' to spring back into itsnormal position, with its end H' across the end of the slide D' for thepurpose of preventing the escapement from operating and allowing thespring A to unwind and the wheel Y to revolve.

Besides doing away with the use of batteries or other constant source ofelectrical energy by using the magneto electric machine, a great savingin the cost of batteries or other eleetromotive power is effected and lam enabled to use much lighter conductingwire than can be used inconnection with a battery. The batteries being of a low tension, a heavyconducting-wire is necessary, and this wire is liable to be broken downby sleet or ice or by violent winds, which is not the case where a steelwire of No. llt or No. 16 gage is used, which l find to be amplysufficient.
